How important is it to keep brass separated by number of time fired?
I ask because yesterday I returned from the range and mistakenly put 15 twice-fired .270 SAKO cases in with about 20 thrice-fired cases.
As a novice, I'm aware I'm being a perahps a bit obsessive (in a good way, generally) about my reloading practice. Should I be bothered by the error, or should I just treat them all as thrice-fired and stop fretting?
Any thoughts gratefully receieved!
